Correction: No cows ever fell from a plane into a Japanese fishing rig

An article on Jan. 16 about drilling for oil off the coast of Angola erroneously reported a story about cows falling from planes, as an example of risks in any engineering endeavor. No cows, smuggled or otherwise, ever fell from a plane into a Japanese fishing rig. The story is an urban legend, and versions of it have been reported in Scotland, Germany, Russia and other locations.
